ft asymmetry in A=12 mirror decay to the 12C 4.4 MeV state
Description
The ratio of the Gamow-Teller beta-decay branches of 12B and 12N to the first excited state of 12C was measured accurately by means of the off-beam β-γ spectroscopy. The ratio of these branches was obtained as 12N/12B = 1.528(27). This gives the mirror asymmetry [(ft)sub(β+)/(ft)sub(β-)]-1 = 0.066(18). The present value together with that for the ground-state decay is discussed in terms of the different radial overlapping. (orig.)
